Really fun game! Easy to start playing but not trivial to be beat. I especially liked that the levels were designed so that the next platform to jump to was not always an obvious choice, but there was also route planning involved.

Controls were responsive and the game clearly fits the theme. Graphics were nice and snow effect really added to the atmosphere. Maybe adding some music / sound effects with help building the atmosphere even further. 

One thing I feel I have to mention, even though it's just a really minor thing: in the menu, it is not clear which button is the selected, I accidentally quit the game the first time (and later again when trying the game second time). Luckily, there's no important other buttons to press than play, so if players just press enter without trying to control the menu, the game starts, so this probably hasn't been a problem with many.

By the way, how many levels there are? I didn't manage to beat it.

It's challenging enough to keep me engaged, the only problems i had were the color-scheme and the lack of save points after each level, but otherwise great game.

Neat little race-the-clock platformer. 

Controls feel responsive, and the margin for error is enough that it feels challenging but fair. My only suggestion at the moment would be to make the platforms a little more contrasting with the background; gray on gray isn't the best.
